Der Laplace Operator

Kompendium der reellen Analysis, 2019
In diesem Kapitel betrachten wir Differentialoperatoren, die in engem Zusammenhang mit der orthogonalen Gruppe der Raumdrehungen im \( {\mathbb{R}}^{n} \) stehen. Zum einen ist dies der sogenannte Laplace Operator \( \Delta = \sum\limits_{i = 1}^{n} {\partial_{i}^{2} } \) , gegeben durch die Summe der zweiten Ableitungen, und zum anderen der Euler ...

A critical Kirchhoff‐type problem driven by a p (·)‐fractional Laplace operator with variable s (·) ‐order

Mathematical methods in the applied sciences, 2020
The paper deals with the following Kirchhoff‐type problem M∬ℝ2N1p(x,y)|v(x)−v(y)|p(x,y)|x−y|N+p(x,y)s(x,y)dxdy(−Δ)p(·)s(·)v(x)=μg(x,v)+|v|r(x)−2vinΩ,v=0inℝN\Ω, where M models a Kirchhoff coefficient, (−Δ)p(·)s(·) is a variable s(·)‐order p(·)‐fractional ...

On The Attainable Eigenvalues of the Laplace Operator

SIAM Journal on Mathematical Analysis, 1999
Summary: We consider the subset \(E\) of \(\mathbb{R}^2\) of all points whose first and second components, respectively, coincide with the first and second eigenvalues of the Laplace operator \(-\Delta\) with zero boundary conditions on domains of \(\mathbb{R}^N\) with prescribed measure. We show that the set \(E\) is closed in \(\mathbb{R}^2\).

Maximum principle for Hadamard fractional differential equations involving fractional Laplace operator

Mathematical methods in the applied sciences, 2019
The purpose of the current study is to investigate IBVP for spatial‐time fractional differential equation with Hadamard fractional derivative and fractional Laplace operator(−Δ)β. A new Hadamard fractional extremum principle is established.
